Casser un morceau de l'immeuble pour améliorer la vue

1982 – Cobalt-60 (possibly from a radiotherapy source) became recycled into steel rebar and used in the construction of buildings in northern Taiwan, principally in Taipei, from 1982 through 1984. Over 200 residential and other buildings were found to have been built using the material.[19] About 7000 people are believed to have been exposed to long-term low-level radiation as a result.[20] In the summer of 1992, a utility worker for the Taiwanese state-run electric utility Taipower brought a Geiger counter to his apartment to learn more about the device, and discovered that his apartment was contaminated.[20] Despite awareness of the problem, owners of some of the buildings suspected to be contaminated have continued to rent apartments out to tenants (in part because selling the units is illegal). Some research has found that the radiation has had an apparent "beneficial" effect upon the health of the tenants based on the death rate from cancers.[21] Another study looking at the incidence of cancer found that although the overall risk of cancer was sharply reduced (SIR = 0.6, 95% CI 0.5 – 0.7), the incidence of certain leukemias in men (n = 6, SIR = 3.4, 95% CI 1.2 – 7.4) and thyroid cancer in women (n = 6, SIR = 2.6, 95% CI 1.0 – 5.7) was greater.[22][23]
